The ROSAT source 1RXS J181333.7+453118 is a Seyfert Sy1 galaxy with a red shift of z=0.093. A ROSAT spectrum and a spectrum over wavelengths of λ4500-7250Å taken with the 2.6-m telescope at the Byurakan Astrophysical Observatory are shown. The x-ray spectrum has characteristics similar to an AGN with a soft x-ray excess.
